Title: Poly:hydroxylated cpds. prepn. from formaldehyde - by condensing in presence of specified metallic cpd. and an alcohol
Inventor: MOEHRING EDGAR DR
IPC: C08K5/05
Filed: 1977-03-30
Abstract: Polyhydroxylated cpds. of low mol. wt. possibly with hydroxyaldehydes and hydroxyketones, are prepd. by the condensation of formaldehyde hydrate in the presence of (I) 0.01-10 wt.% metallic cpd. catalysts and (II) 0-10 wt.% co-catalysts based on cpds. transformable into enediol. This condensation is carried out at 10-150 degrees C in the presence of (II). (I) is a sol. or insol. cpd. of the 1st to 8th sub-groups or 2nd to 4th principal groups of the periodic classification, possibly fixed to high molecular wt. supports. (II) is, at a level of >10 wt.% wrt HCHO, of >=1 mono- or polyalcohols of low mol. wt. and/or polyhydroxylated cpds. of high mol. wt. The reaction is terminated at a residual HCHO level of 0-10 wt.% by deactivation of the catalyst, the catalyst is eliminated and, if desired, the aldehyde and ketonic groups in the prod. are reduced to hydroxy gps. The polyhydroxylated cpds. can be used e.g. as cross-linkers in the prepn. of polyurethane resins, chain elongators, swelling agents, catalysts, to prepare nonionic surfactants, as humectants, anti-freezes, microorganism nutritive media, etc. The method gives 30-75 wt.% polyalcohols in the mixt., without decomposition products. Hydrogenation or redn. of the mixt. is simple and economical, because of the relatively low carbonyl gp. concn. High reproducibility of distribution can be obtd., e.g. mixts. contg. more than 80 wt.% >4C cpds. can be prepd. Colourless prods. are obtd. which can be hydrogenated directly.

Title: Deep freezing industrial wastes e.g. liq. chemicals in containers - providing mixture for controlled combustion in incinerators
Inventor: SCHUSTER ERNST DR ING
IPC: F23G5/02
Filed: 1977-05-07
Abstract: Deep freezing of industrial wastes is accelerated in process carried out in containers with differing contents and unknown compsn. This serves as a pretreatment of the feed to an incinerator. The process involves moving the contents of the container when in the cold zone so that the unfrozen components become uniformly coated with frozen material. Frozen nuclei are introduced during the process in the form of deep frozen solid bodies. When the container is emptied, its contents are deposited on a chilled surface with an area may times greater than the internal surface of the container, to form a shallow bed. Frozen nuclei can also be introduced at this stage. Liquid N2 can be used as refrigerant, the container being immersed in it. Evaporated N2 is allowed to escape without entraining waste with it. Method is for use in incineration plants handling a variety of industrial wastes, esp. chemical wastes. System provides a uniformly controll combustion.

Title: Arc welding two thick metal workpieces - disposed end on one above the other to form a horizontal joint
Inventor: YANOK GEORGE PAUL
IPC: B23K9/23
Filed: 1978-01-23
Abstract: In the formation of a weld between two thick metal workpieces, particularly aluminium, the workpieces are disposed end on, one above the other, so as to form a substantially horizontal joint. At least one of the workpieces has a bevelled joint edge and in forming the joint a consumable electrode is advanced towards the joint while a continuous arc is maintained between the electrode and the metal base at the same time as is provided a protective inert gas screen around the molten metal and the arc. The arc current is of high intensity, the current being produced at a voltage level such that the voltage/current gradient is 70-10 volts per 100 amperes. The current emitted has a reverse polarity and the electrode is advanced at a controlled speed so as to be within 0.75% of the desired speed. The position of the electrode is also controlled so that it is within 2.3 mm of the lower edge of the bevel and the arc is maintained between the end of the electrode and the edge of the bevel. The process enables a weld to be formed with a large weld deposit, at a high speed and having a good quality and is partic. directed to the welding of thick aluminium workpieces without the necessity for finishing the weld by machining.
